==Explanation==&lt;br /&gt;
{{incomplete|This page was created in Lionel Messi's 398th goal. Don't remove this notice too soon.}}&lt;br /&gt;
In the vein of [[605: Extrapolating]], this comic utilizes the incorrect application of extrapolation to produce a ridiculous result. Extrapolation is a form of estimation in which existing data points are used to estimate new data points beyond the range of the existing ones. In this case, [[Randall]] has taken a few data points regarding soccer superstar {{w|Lionel Messi}}'s average goals per game during {{w|FIFA_World_Cup|World Cup}} editions and fit them to a curve using what appears to be polynomial or exponential {{w|extrapolation}}. It illustrates the danger of a small {{w|sample size}}, as the data point for &amp;quot;2026 (so far)&amp;quot; is based on only ''one'' game (the day before this comic, in his inaugural game of the 2026 World Cup, Messi scored three goals against Algeria), and that data point is used to support extrapolation of a rapidly rising number of goals-per-game into the future. The data points for previous World Cups, which bounce around among various values but are all less than or equal to 1.0, are each based on more games, but still pretty small numbers, since Messi made only between three and seven appearances during those World Cups. The results are also likely affected by the nature of the competition's progression, as in the {{w|tournament#group stage|group stage}} a strong team such as Argentina ({{w|FIFA Men's World Ranking|ranked number one}} in the world going into the World Cup) may be expected to score more goals against their randomly-selected opponents (none of whom are in the top 20) than in later stages of the competition where their opponents have overcome other teams in ''their'' groups to be there.&lt;br /&gt;
&lt;br /&gt;
Additionally, the extrapolation pays no attention to the typical career shape of a football player, which would generally tend to show an improvement from youth into their prime playing years, followed by a decline, which can often be quite steep, as they age out. Nor does it allow for variations in the strength of the Argentina team impacting the number of goals Messi is able to score. If the trend shown were extrapolated into the 2050s, it would imply that, far from declining, Messi would be scoring multiple goals per second, which would be impossible in real life,{{Citation needed}} even though Lionel Messi is widely considered one of the best players in football.&lt;br /&gt;
&lt;br /&gt;
The claim in the title text that this World Cup is the last one in which Messi will face serious competition is likely true, but not in the sense that the extrapolation might suggest. That implies that in future World Cups Messi would theoretically score hundreds of goals per game, likely eclipsing any other player's scoring rate. It may even be suggesting that, on his own and regardless of the rest of his team, his ability can triumph over any other national team fielded in the World Cup. In reality, he will likely not face ''any'' competition in future World Cups as this is likely Messi's last World Cup, period.&lt;br /&gt;
